In Act III, scene 2, Hamlet has a brief conversation with Polonius just after everyone comes in to watch the play Hamlet has arranged. Hamlet is in a good mood and feeling witty, since he expects to find out whether Claudius is guilty of killing his father.

Hamlet: [To Polonius] My lord, you played once i' the university, you say?

Polonius: That did I, my lord, and was accounted a good actor.

Hamlet: What did you enact?

Polonius: I did enact Julius Caesar: I was killed i' the Capitol; Brutus killed me.
